Comparison of ORs for Developing Overall and Airway Adverse Events in Preterm and Term Patients in Patients 0 to 36 Months of Age

Event	0 to 6 mo		7 to 18 mo		19 to 36 mo
	Preterm	Term	Preterm	Term	Preterm	Term
Any adverse event	2.63	0.38a	1.71a	0.59a	1.30	0.77
Apnea	5.26a	0.19a	2.37	0.42	5.19a	0.19a
Oxygen desaturation	1.33	0.75	2.77a	0.36a	1.98	0.51
Airway obstruction	1.56	0.64	1.29	0.77	2.22	0.45
Cough	1.46	0.68	0.94	1.06	1.41	0.71
Secretions	3.15	0.32	1.98	0.51	1.40	0.71

Patients in the 0- to 6-mo age category were at highest risk for developing adverse events. The occurrence of apnea was dramatically higher in preterm infants. The odds of preterm children developing oxygen desaturation increased after 6 months of age, suggesting that this group has decreased reserve compared with term children of similar age. There were no incidents of laryngospasm, bronchospasm, or snoring in the preterm group 0 to 6 mo of age.
